I’ve successfully deployed my Strapi app over to both Digital Ocean and Railway.app. I found migrating my PostgreSQL database over from Heroku to either of these platforms very easy.
The migration over to Digital Ocean was a bit more involved than moving it to Railway, as I decided to use Dokku as the runtime environment there (using the Dokku-specific droplet). But after a day of fiddling with it, it turned out to be not too bad and it’s happily running over there right now. I will let the app run on both alternative platforms until mid November, and will decide which one to keep based upon final costs, etc, but if I were to pick a platform right now I think Railway will land up being the one I go with.
